Hey again, Bob,
When I had dial-up, download managers became my best friends, allowing me to pause a download, continue a download after the connection was lost, and speed up the download by making multiple connections for maximum efficiency. I used to use FlashGet, but it now comes packed with adware, so I recommend the free download manager Free Download Manager. It is simply named and simply designed, but it gets the job done with features you wouldn't expect from a free product. You'll no longer have to worry about dropped connections or large downloads, and will be able to surf the net or perform other tasks while downloading without worry.
I have tried to download a very large file three times. I have a dialup connection and this is disrupting my computer usage(I try not to use my computer while I am downloading). I have lost my connection each time leaving a unfinished dowlaod file. Is there a way or program to continue the dowload from where it left off?
